Maryland State Police said the crash happened shortly before 9:30 a.m. on the northbound shoulder of Route 152 in Joppa, near the I-95 southbound ramp.

Police said a driver of a 2004 Pontiac pulled onto the shoulder of Route 152 after experiencing a tire blowout on the driver's side of the vehicle. Authorities said after parking the disabled vehicle about 10 to 15 feet off the roadway, the motorist called John Scott, 54, of Abingdon, for assistance.

Scott arrived around the same time as 41-year-old Walter Feick, who is a vehicle recovery technician with the Maryland Transportation Authority Police. Detectives said Feick happened upon the disabled driver while on patrol, so he and Scott both began working to replace the blown-out tire.

For unknown reasons, police said a motorist driving a Volkswagen exited from the I-95 southbound ramp onto Route 152, heading northbound, when she lost control and skidded into the disabled vehicle, hitting both men. Police said they believe Feick and Scott were on the driver’s side of the vehicle working on the tire, and the owner of the disabled vehicle was in the backseat.

Scott was pronounced dead at the scene, and Feick was transported to Shock Trauma, where he is listed in stable condition. The owner of the disabled vehicle and the operator of the Volkswagen refused medical treatment at the scene.

Authorities said the identities of the two others involved in the crash are being withheld due to the ongoing investigation. Police believe the fog and wet roads played a role in the crash.

According to Scott's Facebook page, he is a retired police officer who was working as a maintenance worker at Mountain Christian Church, which sits about a mile from where he died.

The ramp from southbound I-95 to northbound Route 152 was closed for more than three hours while authorities worked to clear the scene.
